Are you sure about this? I am aware that manpower growth will increase retirement in that way that there are more people that can retire. But that is not what i mean. The retirement can change within a day if a minister is changed. Here an example:
Playing china i have a total manpower of 13613.7. That should be enough to deal with "rounding errors". By Agrotechs i have a multiplicator of 1.2. By full defence lobby i have another multiplicator of 1.1. I also have the ministers man of the people(+10%) and school of mass combat(+25%). So there is a total multiplicator of 1.2 x 1.1 x (100%+10%) x (100%+25%)= 1.815. Am i right so far?
There retirement shown in the mouse over at the manpower symbol says i have a daily retirement of 2.47. Now i change the chief of staff giving me a total multiplicator of only 1.2 x 1.1 x (100%+10%) = 1.452. Now the daily retirement shown in the mouse over has shrunk to 1.98 and the total manpower is still 13613.7. So the retirement shown in the mouseover seem to be calculated by (total manpower) x (tech modifier) x (defence lobby modifier) x (security minister modifier) x (chief of staff minister modifier) x (national identity modifier) x (social policy modifier) x (national culture modifier) x 0.0001.
There is a slight possibility that the retirement shown is not the real retirement, but i don't think so.
*sigh* ... let's review :
1) Aging is a factor applied to all of the manpower in the realm. Its value is a fraction of the total manpower.
That means if you have 100 manpower everywhere ( pool,military,buildings ) and zero growth and zero drains and the aging factor is 0.01 (1%) , you will lose 1 manpower to aging.
2) Manpower growth increases your manpower ( if it outpaces reinforcements drain ).
That means that if your growth is 10 manpower (and no other drains), your manpower base is 100 + 10.
Aging is applied to 110. That means 1,1 manpower lost to aging.
But what if your manpower growth is 20?
Then of course the aging base is 100 +
20 and that results to manpower lost to aging being 1,
2.
Again, where is the issue? Yes, manpower growth increases your manpower ( I can't believe I'm typing such an obvious truism ).
Bigger growth => more manpower => bigger aging.
Really, isn't it elementary maths that if you divide a
bigger number (more manpower due to more growth) by the same ratio, you get a
bigger remainder ( more manpower lost to aging in absolute value )?
